What's New in ByteFast
4.0
October 12, 2026
ByteFast 4.0 is our biggest update yet. NEW LOOK FOR YOUR PROGRESS • Choose how your fast is shown: a ring, a bar, or an hour-by-hour grid that fills in as each hour passes. It works on your iPhone, widgets and Apple Watch. • Pick your color: Leaf (green) or the new Ocean (blue). • A fasting-phase timeline shows where you are and how long until the next phase. SMARTER STATISTICS • Rebuilt with clear charts for your fasting hours, fast length over time, outcomes and break reasons. • See Week, Month or All-time views, plus your streaks, averages and longest fast. HANDS-FREE • Ask Siri to start or end a fast, or to tell you how long you've been fasting. • Start and end fasts from a new Control Center toggle. If you end a fast under 4 hours (which isn't saved), ByteFast asks you first. EVERYWHERE YOU LOOK • Your Live Activity now appears in the Apple Watch Smart Stack and on CarPlay. • Lock Screen widgets show your last fast when you're not fasting. ACCESSIBILITY • Full VoiceOver support across the app, widgets and Apple Watch, and text that scales with your size setting. SMALLER IMPROVEMENTS • The same break-reason choices on iPhone and Apple Watch, so your statistics group them correctly. • Faster, more reliable syncing between iPhone and Apple Watch. • Bug fixes and polish throughout.
